/*
string sprintf(string format[mixed arg1[, mixed arg2[,...]]]) works somewhat like the C-family
function of the same name. The placeholders in the format string are marked by "%" and are
followed by one or more of these elements, in this order:
1. An optional "+" sign that forces to preceed the result with a plus or minus sign on numeric values. By default,
only the "-" sign is used on negative numbers.
2. An optional padding specifier that says what character to use for padding (if specified). Possible values are
0 or any other character precedeed by a '.'. The default is to pad with spaces.
3. An optional "-" sign, that causes sprintf to left-align the result of this placeholder. The default is to
right-align the result.
4. An optional number that says how many characters the result should have. If the value to be returned is
shorter than this number, the result will be padded.
5. An optional precision modifier, consisting of a "." (dot) followed by a number, that says how many digits should
be displayed for floating point numbers. When used on a string, it causes the result to be truncated.
6. A type specifier that can be any of:
* % - print a literal "%" character
* b - print an integer as a binary number
* c - print an integer as the character with that ASCII value
* d - print an integer as a signed decimal number
* e - print a float as scientific notation
* u - print an integer as an unsigned decimal number
* f - print a float as is
* o - print an integer as an octal number
* s - print a string as is
* x - print an integer as a hexadecimal number (lower-case)
* X - print an integer as a hexadecimal number (upper-case)
7. For example, to get a two-digit string representation of a byte value, use
sprintf("%02.2X", my_number), where:
% - placeholder marker
0 - pad with 0
2 - width specifier (a minimum of 2 characters)
.2 - precision modifier, (a maximum of 2 characters)
X - show an integer as an upper-cased hexadeciaml value
